     (wherein R 1 , R 2 : an alkyl which may be substituted, an aryl which may be substituted, etc.; R 3 , R 4 : H, an alkyl which may be substituted, etc.; X: halogen, an alkyl which may be substituted, etc.; Y: halogen, alkyl, etc.; n: 0 to 4; m: 0 to 6) or a salt thereof, and at least one of fungicidal compounds selected from the group consisting of a Strobilurin series compound, a triazole series compound, etc., as effective ingredients.

TECHNICAL FIELD

The present invention relates to a plant disease control compositionwhich comprises (Group a) at least one quinoline compound represented bythe formula (I) or a salt thereof and (Group b) at least one fungicidalcompound selected from the group consisting of Group 1 (b-1) to 28(b-28) as effective ingredients and a method for controlling plantdiseases by applying the composition.

BACKGROUND ART

A number of chemical agents have heretofore been used for controllingplant diseases. However, the problem that plant pathogens have acquiredresistance to the chemical agents becomes remarkable due to frequent useor excessive application, etc., of the chemical agents having similarstructures and same functions for controlling the same kinds ofdiseases.

On the other hand, consumers' needs for agricultural chemical-reducedcrops and social needs to reduce environmental loads due to agriculturalchemicals have now increased.

Also, in a farmer's field where the chemicals have been actually used,when two or more kinds of chemicals are used in admixture for thetreatment by the tank mix method, there are many risks to lower theeffect of the other chemical to be mixed with each other orpossibilities to cause chemical damages against plant materialsdepending on a combination of chemicals where they are not well-suitedto each other.

Under such a situation, it has been desired to develop a plant diseasecontrol composition having high effects against fungi or bacteria whichare resistant to existing chemicals, and having high effects with a lowamount of an effective ingredient. Moreover, for the purpose ofpreventing plant pathogens from obtaining resistance, it has also beendesired to develop a plant disease control composition comprisingcomponents (compounds) having different basic structures and differentfunctions with well-suited to each other, and a method for controllingplant diseases.

It has been known that a quinoline compound represented by the formula(I) shows, as a fungicide, controlling effects to rice blast(Pyricularia oryzae) and gray mold (Botrytis cinerea) of tomato,cucumber and kidney bean, etc., by an application method such as seeddisinfection, foliar spray treatment, etc. (Patent Literatures 1 to 4).

However, it has never been known yet about a controlling effect of thequinoline compound represented by the formula (I) and the otherfungicide(s) in admixture.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention

The present inventors have investigated a combination of the quinolinecompound represented by the formula (I) and the other fungicidalcomponent(s), and as a result, they have found that by combining thequinoline compound represented by the formula (I) and a specificfungicidal compound(s), excellent controlling effects (synergisticeffects) against various plant pathogens can be obtained, which couldnever be expected from the single component alone, stable prophylaxiseffect can be obtained against the existing fungi and bacteria resistantto chemicals, and no chemical damage to plants occurred to accomplishthe present invention.

An object of the present invention is to provide a novel plant diseasecontrol composition having a broad spectrum against various kinds ofplant pathogens, having high plant disease controlling effects againstexisting fungi and bacteria resistant to chemicals, showing highactivity even when amounts of effective ingredients to be applied toenvironment where fungi or bacteria are living are low, and showing nochemical damage against plants, and a method for controlling plantdisease by appling the composition.

The plant disease control composition of the present invention givessynergistic controlling effects as compared to the case where eacheffective ingredient is used alone.

The plant disease control composition of the present invention may beused as such, but it is generally used by mixing with a carrier, anddepending on necessity, by adding an auxiliary for preparation such as asurfactant, wetting agent, fixing agent, thickener, antiseptics,colorant, stabilizer, etc., to prepare a wettable powder, flowable,water dispersible granule, dust formulation, emulsifiable concentrate,etc., according to the conventionally known method and used suitably. Acontent of the quinoline compound (I: compound of Group a) as aneffective ingredient in these preparations is generally in the range of0.005 to 99%, preferably in the range of 0.01 to 90%, more preferably inthe range of 0.1 to 85% in a weight ratio. Also, a content of thefungicidal compound of Group b as an effective ingredient in thesepreparations is generally in the range of 0.005 to 99%, preferably inthe range of 0.1 to 90% in a weight ratio, and a sum of the quinolinecompound (I: compound of Group a) and the fungicidal compound of Group bis generally in the range of 0.005 to 99%, preferably in the range of0.01 to 90%, more preferably in the range of 0.1 to 85% in a weightratio. A mixing ratio of the quinoline compound (I: compound of Group a)and the fungicidal compound of Group b is generally 0.01 to 1000 of thefungicidal compound of Group b based on the quinoline compound as 1,preferably 0.1 to 100 of the fungicidal compound of Group b based on thequinoline compound as 1 in a weight ratio.

In the plant disease control composition of the present invention, atotal content of the effective ingredients including the quinolinecompound (I: compound of Group a) and the fungicidal compound of Group bmay vary depending on the form of the preparation, and generally 0.01 to30% by weight in the dust formulation, 0.1 to 80% by weight in thewettable powder, 0.5 to 20% by weight in the granule, 2 to 50% by weightin the emulsifiable concentrate, 1 to 50% by weight in the flowablepreparation, and 1 to 80% by weight in the dry flowable preparation. Itis preferably 0.05 to 10% by weight in the dust formulation, 5 to 60% byweight in the wettable powder, 5 to 20% by weight in the emulsifiableconcentrate, 5 to 50% by weight in the flowable preparation, and 5 to50% by weight in the dry flowable preparation. A content of theauxiliary is 0 to 80% by weight, and a content of the carrier is anamount in which total contents of the compounds of the effectiveingredients and the auxiliary are deducted from 100% by weight.

The carrier to be used in the above-mentioned composition means asynthetic or natural inorganic or organic substance to be formulated forthe purposes of helping the effective ingredients to be reached to theportion to be treated, and making storage, transport and handling of thecompounds of effective ingredients easy.

Test Example 1 Tomato Gray Mold Preventive Test (Diethofencarb-ResistantStrain)

In a greenhouse, tomato (variety: Ohgata-Fukuju) planted in a plasticpot having a diameter of 5 cm was grown to the 2nd to 3rd-leaf stage.Wettable powder prepared according to Preparation example 1 andPreparation example 2 were diluted to a predetermined concentration withwater, and sprayed with a spray gun with 10 ml per 2 pots. After dryingthe chemical liquid, a conidiospore suspension prepared from Botrytiscinerea (Diethofencarb-resistant strain) which had been previouslycultured on a MY medium were inoculated by spraying. After inoculation,the pots were placed in a high-humidity chamber (20 to 22° C.), andafter 2 days, the pots were taken out and controlling effects wereexamined. In the examination, a ratio of lesion area occupied per wholeleaflet of tomato was determined according to the indexes of thefollowing mentioned degree of diseases. Also, from the average degree ofdiseases of each treated district, the control value was calculated fromthe following numerical formula. Incidentally, as a comparison, Wettablepowder prepared according to Comparative preparation example 1 andComparative preparation example 2 were similarly tested, and controllingeffects were examined. The results of the spreading test and thetheoretical value according to the Colby's formula are shown in Table 3.

Index of Degree of Disease

Index Degree of disease

0 No lesion

1 Lesion area is less than ⅓ of whole leaflet

2 Lesion area is ⅓ or more and less than ⅔ of whole leaflet

3 Lesion area is ⅔ or more of whole leaflet

Incidentally, average values of the each treated district andnon-treated district were used as the degree of diseases.

The control value was calculated from the following formula.

Control value=(1−Ratio of diseased leaflets in the treateddistrict/Ratio of diseased leaflets in the non-treated district)×100

Here, Colby's formula is X=P+Q−P×Q/100, wherein X is a theoretical valueof the control value, P is a control value where a certain chemical isspread alone, and Q is a control value where chemicals to be used incombination are spread in admixture.
